brightness control stopped working (hardy)

[Nuno Donato]

I could control the brightness of my laptop screen using hotkeys (Fn+Home/End), although the panel applet never worked (dont know why).
Sometime ago, the brightness control using the hotkeys also stopped working.

sudo dmidecode -s system-manufacturer
LG Electronics

sudo dmidecode -s system-product-name
E200-A.CP20P

sudo dmidecode -s system-version
0100

I know they are being detected, because I did a tail -f /var/log/acpi I this is what I got when I press one of them:

Thank you for your bug report and the additional info you've provided.
I'm marking it as duplicate of bug 217504, which is about acpi_fakekey failing/being ignored, which gets called in /etc/acpi/video_brightnessup.sh.
